The susceptibility to dampness of BiBO is incredibly very low. Nevertheless, buyers are suggested to offer dry conditions for both of those use and storage of BiBO to extend the life time. Water condensation on crystal surfaces should be Certainly avoided at any time.
Inertness to Dampness: BIBO crystal is inert to dampness, which means it does not degrade or lose its optical Houses when exposed to humidity. This will make BIBO a far more secure and dependable option for optical purposes in several environments.

Crystal life time can even be strongly depending on the material high-quality, Though selected degradation phenomena appear to be intrinsic constraints of the fabric.
Also, it might be highly appealing to make use of a crystal substance which can be critically period-matched at space temperature simply because noncritical section matching generally requires the Procedure with the crystal within a temperature-stabilized crystal oven. Nevertheless, the feasibility of vital section matching may be supplied only for adequately large peak powers.
GWU-Lasertechnik has a lot more than 30 yrs of expertise in distributing laser crystals. Decide on GWU to take advantage of our wide expertise As well as in-subject knowledge!
At the moment, as A sort of fantastic nonlinear next harmonic crystal, it can be employed to provide high effectiveness crystal of eco-friendly or blue laser.
Procedure of nonlinear crystals at temperatures underneath place temperature (to realize stage matching) is usually problematic, as it may produce condensation of drinking water within the crystal surfaces In the event the bordering air will not be quite dry.
In the case of ultrashort pulses the high group velocity mismatch enforces using a shorter more info crystal, which requires superior optical intensities for a given conversion performance.
Excessive optical intensities for the duration of operation could instantaneously harm a crystal. Sadly, nonlinear crystals often should be operated not considerably from their optical problems threshold to realize a sufficiently high conversion performance. This means a trade-off among conversion efficiency and crystal life span.
Bismuth Triborate (BiB3O6 or BIBO) is really a newly designed nonlinear optical crystal. It possesses substantial effective nonlinear coefficient, higher injury threshold and inertness with regard to humidity.
China BIBO crystals can be employed not just as substantial-performance frequency doubling and frequency summing gadgets, but even have wide software prospects in the sector of optical parametric oscillation (OPO), and it also has a vital software in the effective era of ultrabright entangled photons by blue pumped Spontaneous Parametric Down Conversions (Also Know as SPDC).
The magnitude of the powerful nonlinear coefficient depends upon the nonlinear tensor parts and around the used section-matching configuration. A high nonlinearity is significant especially If your achievable optical intensities are low.
Because the 2nd harmonic (SHG) might be widely utilized to create coherent visible gentle and ultraviolet radiation, individuals listen to it, but the standard nonlinear crystals such as KDP, LBO, KTP, B-BBO even have many shortcomings. BIBO crystal is a different sort of nonlinear crystal. As opposed with KDP crystal, it can make up for the drawback that KDP crystal can grow in massive size but dissolve in drinking water.
